i bought a ball and spring controller for my 1.6 td and need a little help expaining how it needs to be hooked up..
one side says to hook to a boost source. can i run it off the intake? can it be run from the same nipple the boost gauge is reading boost or does it need its own nipple off the intake?
the other end of the controller needs to be run to the waistegate...how? where on the waiste gate? i have a garrett t3.
thanks jason

there should be a line going from the compressor housing to the wastegate. Tap into that

A linear opening valve style wastegate usually flows some air around the valve stem to cool it, so it is best not to skimp on the size of the air supply line feeding the wastegate or it could cause a pressure drop. In this case your other accessories (IE: boost gauge) tapped off the same inadequately sized line will see less than full manifold pressure.
FYI: for Tial-style aftermarket external wastegates, the recommended hose size for the pressure supply is 1/4". This also seems to be the same size used by Garrett and KKK on their internal wastegates, if not 5/16".
You can see how I tapped to the intake manifold "el" for a manifold pressure wastegate pressure signal here:

ok im a bit lost because im not real familiar with all the options and ways of tuning or setting up a turbo. lets just say in a basically stock formed 1.6td motor, and you were me, :shock: how would you hook a boost gauge and one of these adjustable valves up?
i drilled and tapped a nipple on the compressor just like you did for the boost gauge, but i used a small fitting that works with the small clear plastic line that comes with the gauge. is this too small, do i want to just run something bigger anyway? and yes im running an intercooler too. thanks for your help and time

The simplest way to hook up a boost gauge on a stock 1.6lTD would be to "T" into the LDA (injection pump boost enrichment) sensor hose, and the simplest way to install a manual boost controller on same motor would be to install it inline with the wastegate pressure sensing hose (this would be the large hardline on KKK turbo or rubber hose on Garrett turbo that runs from a fitting on the compressor housing to the wastegate.)

Hi all. If you just tee into this line, will it not still bleed off through the wastegate which has less resistance than the boost controller??? I guess i'm missing something here?
?? cheers..Shane

Hi all. Still struggling with this :-( Can i just cut the small steel pipe and install an inline regulator??? If i do this, it won't bleed off to atmosphere as some posts suggest it should??? Alternatively can i remove the steel pipe altogether and just run a pipe from the torbo housing to the regulator and not worry about the wastegate at all??? Any pictures would be greatly appreciated, Cheers guys..Shane ( KKK24 by the way )

i put mine on the rubber hose coming from the compressor housing and going to the wastegate. I removed the hose from the compressor housing and installed it on the controller and then made a new line from the controller back to the compressor housing. Took 2 minutes to install and if i ever want to take it off all i have to do is un hook it and reinstall the wastegate line to the compressor.

So did you simply cut the pipe in the middle and put one end of the pipe into one side of the regulator and the other part of the pipe into the other side of the regulator??? Cheers..Shane

I believe this is how it works. I haven't done it but I imagine that it has to be pressure side, regulator, wastegate. just guessing

Thanks so much for the reply. The only thing i don't understand now is what people were talking about when they said they were venting it out to atmosphere because this way doesn't does it?
?? :? :? :? :? :?

wow....
Perhaps some of us are not understanding your question
(or read Boost controller as boost GAUGE!)
Look up
www.hallmanboostcontroller.comfor detailed instructions.
You need to interrupt the signal (air) to the wastegate.
There will be a rubber hose from the wastegate to the compressor housing (on all turbos).
On my T3, there is a 5/16 rubber hose about 2-3" long.
I removed it, and put the boost controller there.
easy stuff.
Enjoy!

Thank you so much for your reply, i'll check that out now. By the way, my turbo has a steel pipe not a rubber one. cheers..Shane
